A sweat sensing device () comprises at least one sweat generation unit () capable of initiating sudomotor axon reflex (SAR) sweating in an indirect stimulation region and at least one analysis unit () capable of sensing a physiological parameter of sweat, collecting a sweat sample, or a combination thereof. The at least one analysis unit () is located above the indirect stimulation region when the sweat sensing device is placed on skin.

Devices for integrated indirect sweat stimulation and sensing

A sweat sensing device includes a plurality of sweat collection pads communicating with a sensor. Each of the pads is activated by a timing circuit which allows one or more of the pads to be activated at a selected time and subsequent deactivated after a defined period of time. This allows for selective collection of sweat from a plurality of pads over a prolonged period of time. An impedance measuring circuit can be employed to determine if one or more of the pads becomes disconnected, in order to avoid irritation. Further, the devices can use a common microfluidic device which both transports sweat activating substance, such as pilocarpine, to the surface of the skin and directs sweat away from the skin to a sensing device.

Devices for integrated, repeated, prolonged, and/or reliable sweat stimulation and biosensing

A sweat sensing device includes at least one sweat generation unit capable of initiating sudomotor axon reflex (SAR) sweating in an indirect stimulation region and at least one analysis unit capable of sensing a physiological parameter of sweat, collecting a sweat sample, or a combination thereof. The at least one analysis unit is located above the indirect stimulation region when the sweat sensing device is placed on skin.
